FAQ: Can I run 4-pin PWM fans on 3-pin fan headers? Yes! ... When connected to 3-pin fan headers, the fan will run at full speed (unless the mainboard supports voltage based speed control).
Can a 4 pin go into a 3 pin?
You can plug a 4-pin PWM fan connector into a 3-pin terminal on the motherboard without any problems. Without the fourth pin connected, the fan will just run at full speed.Oct 15, 2013
Can you mix 3 pin and 4 pin fans?
Please Note: You can connect a 3 Pin Fan to a 3 Pin or 4 Pin header on the motherboard. The fan will function normally no matter type of fan header is used.
Are fan splitters bad?
You will be safe using a fan splitter as long as you the fans you are connecting does not draw more current than the motherboard header provides.Feb 15, 2017
Do PC fan splitters reduce speed?
No, they will all run the same speed.Dec 11, 2012
How does a DC splitter work?
A splitter takes RF power from an input and divides it up between multiple outputs. The splitters are designed to operate at a certain range of frequencies. For cable TV, this might be from 5 MHz to 900 MHz.Oct 13, 2012
What does a fan splitter cable do?
You haven't told us if you are using 3 pin or 4 pin fans. A fan splitter uses one of the pin 3 (tach) signals to send the motherboard fan speed. It can control fan speed on the PWM pin 4. A fan splitter will split pins 1,2 and 4 to every fan, and pin 3 from the first fan.
Do splitters reduce power?
splitter do not reduce power it only split between the 2 fan and they receive ful power but it will only read one speed sensor for one fan .Jun 9, 2016
Is it okay to split fan headers?
Yes, you can. 3-pin fans are 100% compatible with 4-pin headers, and generally speaking the 4-pin header is keyed so as not to damage the motherboard or fan if a 3-pin fan is incorrectly connected. Do keep in mind, though, that you might loose fan speed control with that setup.Jun 3, 2011
How many fan splitters can I use?
So there's a "rule of thumb": you can connect up to TWO fans (normal ones) to any mobo fan header, but NOT MORE. That is why a Y-splitter with only two outputs can work. Although you can buy splitters with more than two output connectors, DO NOT use them!Jun 8, 2016
Are fan splitters needed?
Reputable. Don't use a splitter. Your motherboard probably can't handle 5 fans on one fan header, especially if 2 are LED fans. Instead, plug the fans straight into the power supply with MOLEX connectors.May 11, 2014
